What was the resistance of the resistor in Part 1? Include your current-voltage plot with the measured slope in your response. Explain how you might determine the equivalent resistance of two resistors in series or parallel with this technique.

calculate the slope of the line and the slope is equal to the resistance of the circuit   m=R

Explanation:

One method for measuring the resistence is to use ohm's law

             V = R I

              y = mx  +b

             b=0

             m = R

Where we measure various values of voltage and current, with these values we can make a graph of V vs I where we calculate the slope of the line and the slope is equal to the resistance of the circuit

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
